Add System.Environment.getExecutablePath
As agreed after the corresponding libraries@ discussion (http://thread.gmane.org/gmane.comp.lang.haskell.libraries/17368) we should add System.Environment.getExecutablePath. Attached is an implementation for OS X, Linux, and Windows, with a fallback to argv[0] on other platforms.
The Windows implementation was written without access to a Windows machine, so someone will need to test it on Windows to make sure it compiles/works.
